Abstract
(EN)
The present invention relates to the technical field of cells, and discloses a method for preparing a direct ethanol fuel cell. The method comprises the following steps: synthesis of a catalyst: mixing a silicon dioxide powder, sucrose and trithiocyanuric acid, preheating same to obtain a mixed powder, then adding Teflon thereto and mixing same with the mixed powder, and heating the mixture of the mixed powder and the Teflon to obtain an N,S-codoped carbon catalyst; synthesis of an electrolyte: using an initiator to subject sodium acrylate to a polymerization reaction, and soaking a hydrogel product obtained by the polymerization reaction in a strong alkaline solution; preparation of a cathode: coating the N,S-codoped carbon catalyst onto a collector electrode to obtain the cathode; preparation of an anode: coating a Pt-Ru/C catalyst onto a collector electrode to obtain the anode; and preparation of a cell: sandwiching the soaked hydrogel between the cathode and the anode to obtain the cell. The cell of the technical solution has a very high flexibility, a high power density, and a function of using while dropping.
